Single-Family vs. Condo: Marathon's Two Different Markets
When I compare homes across Marathon, from canal-front single-family properties near Sombrero Beach to condo units around Boot Key Harbor, the market tells two very different stories this month.
July 2026 Takeaway: Marathon single-family sales cooled while new listings climbed 39% year-over-year, and the condo/townhouse segment stayed thin enough that a handful of sales swings the percentages sharply.


Marathon Single-Family Homes: Slower Pace, Selective Buyers
| Metric | Value | YoY Change |
|---|---|---|
| Active Inventory | 147 | ↓ -2.6% |
| Pending Inventory | 24 | ↓ -7.7% |
| Closed Sales | 16 | ↓ -16% |
| New Listings | 25 | ↑ +39% |
| New Pending Sales | 16 | ↑ +33% |
| Median Sale Price | $980,000 | ↓ -27% |
What I'm seeing on the ground: closed sales and median price both pulled back from a year ago, even as new listings and new pending sales climbed. More sellers are testing the market from Grassy Key down to Vaca Key, but buyers are staying selective on price before committing.
Marathon Condos & Townhouses: A Thin, Volatile Market
Because our condo market in Marathon operates on relatively low overall transaction volume, a shift of just a few closings creates a large percentage swing on paper. With only 8 closed sales this month, it's a thin segment where a single month's numbers rarely tell the whole story.
| Metric | Value | YoY Change |
|---|---|---|
| Active Inventory | 55 | ↓ -29% |
| Pending Inventory | 3 | ↑ +200% |
| Closed Sales | 8 | ↑ +300% |
| New Listings | 9 | ↓ -25% |
| New Pending Sales | 2 | ↑ +100% |
| Median Sale Price | $742,500 | ↓ -34% |
Single-Family vs. Condo: What the Contrast Tells Us
For buyers weighing the trade-offs between low-maintenance condo living and managing a single-family property with dockage, the entry point for Marathon ownership remains distinctly split. You're looking at a median price gap of roughly $237,500 between condos and single-family homes, though both segments pulled back from last year's pricing, single-family by 27% and condo by 34%. Single-family remains the larger, more established segment, with more than double the closed sales and nearly triple the active inventory of condos and townhouses this month.
